Verdict

The call

The clearest difference is update cadence: CaffeineLog at every 2 days against Caffeine App's monthly. CaffeineLog also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 74%). Caffeine App's advantage is ratings volume (341 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
